Chrysler's St. Louis, Mo., truck and minivan assembly complex found more benefits than expected when it met the first of two objectives by having the U.S. Department of Energy conduct a steam-system assessment at the plant. The second goal was to get plant personnel comfortable with the DOE's suite of steam evaluation software and use it consistently.
The facility optimized the boiler operation and implemented a load-management strategy. Team members lowered flue-gas oxygen content in one boiler, reduced boiler blowdown and implemented an ongoing steam-trap inspection and repair program. The results were:
- $727,000 annual energy savings.
- 70,000 MMBTU annual natural gas savings.
- Two-month simple payback.
